Question

我试图从我的java项目向服务器发送Json请求，问题是，我找到了一个人写的类，他使用Apache，我试图建立apache的路径，但它仍然不会导入这些东西：

    import org.apache.http.HttpResponse;
    import org.apache.http.client.methods.HttpPost;
    import org.apache.http.entity.StringEntity;
    import org.apache.http.impl.client.DefaultHttpClient;

这是班级：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.net.MalformedURLException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;


public class JsonHTTPRequest {
    private static String postToURL(String url, String message, DefaultHttpClient httpClient) throws IOException, IllegalStateException, UnsupportedEncodingException, RuntimeException {
        HttpPost postRequest = new HttpPost(url);

        StringEntity input = new StringEntity(message);
        input.setContentType("application/json");
        postRequest.setEntity(input);

        HttpResponse response = httpClient.execute(postRequest);

        if (response.getStatusLine().getStatusCode() != 200) {
            throw new RuntimeException("Failed : HTTP error code : "
                    + response.getStatusLine().getStatusCode());
        }

        BufferedReader br = new BufferedReader(
                new InputStreamReader((response.getEntity().getContent())));

        String output;
        StringBuffer totalOutput = new StringBuffer();
        System.out.println("Output from Server .... \n");
        while ((output = br.readLine()) != null) {
            System.out.println(output);
            totalOutput.append(output);
        }
        return totalOutput.toString();
    }
}
